Application filed June 11, 3912. Serial No. 708,085.

To all whom 2'2? may concern lie it known that l, .l'osnru LMRUIX. acitizen of the United States. residing at Fall River, in the county ofBristol and State of h'l asmwhusetts, have invented a new and usefulImprovement in Friction Devices for Shuttles, of which the following isa specification.

This invention relates to certain new and useful improvements infriction devices for shuttles and the object. of the invention is toprovide a friction device of simple and economical structure which iscapable of use with tine or coarse yarn and which is so constructed thatany desired amount of friction may be obtained by simple adjustment ofthe friction device.

In the drawings-l*igure l is a top plan view. .l ig. 2 is a sideelevation, partly in section. Fig. 3 is a section taken on the line 3-3of Fig. 2 looking toward the point of the shuttle. Fig. l is a Viewsimilar to Fig. 3 but; looking toward the shuttle bob bin cavity.

The shuttle 1 has a. throat 2 that leads from the bobbin cavity 3 to thethreading slot the latter terminating in the delivery eye (J.

The friction device consists of a tubular post 6 that is formed with apair of dia--- metrieally opposed slots 7 and. R that extend inalinement with the longitudinal axis of the post, both of the slotsextending through the upper end of the post and terminating at a pointsubstantially central of the length of the post. The slot 8 ln'minatesatv its inner end in a circular hole it the bottorof which is disposedin a point slightly below the bottom of the slot 7; The hole 5') oil thepost (3 is loeate tl adjacent the bottom cavity The. lower end 01 thepost is exleriorly threaded at 10 and is formed with slots 11 to receivethe serew driver point, whereupon the screw threaded portion ll) whichis engaged in an internally thrlmded socket 12 that extends up throughthe bottom of the shuttle into the throat 2 thereof. may be turned inthe socket ii! in an obvious manner.

The thread engaging device Consists of a member that has a base 13 whichis eireular in cross section and which is conlorn'ulhly engaged in theboreol post l. The upper end of the thread engaging device is formedwith a hook shaped end 14 that is connected by a shank 15 with the base13, the hook shaped member 14 extending across the slots 7 and 8, asdepicted in Figs. 3 and 4. The thread engaging device is adjustablelongitudinally of the post 6.

In case of the use of coarse yarn a screw driver can be inserted intothe upper end of socket 12 and engaged with the'slots 11:t0 turn thepost and thereby cause the slots 7 and 8 to assume a relative angularposition with respect to the throat .2 to give any desired degree offriction.

l-laving thus described my invention, I

claim as new and desire to secure by Let-- tors Patent- 1. A frictiondevice for slulttles, consisting of a tubular post exteriorly threadedat one end and having its opposite end provided with a pair oflongitudinal oppositely disposed slots, one of said slots having itsinner end terminating in a round hole, and adjustable thread engagingmeans on the interior of said post said thread engaging. member having;a portion, which extends across each oi the slots and is adapted to haveits under side engage the thread.

2. A friction device for shuttles, c0nsist-- ing of a tubular postexteriorly threaded at one end and having its opposite and provided witha pair of longitudinal oppositely disposed slots, one of said slotshaving its inner end termiiniting in a round hole, and

a thread engaging member on the interior of the post having a base thatis conformnbly fitted in the post. at one end thereof, a

shank Formed on the base, and a hookshaped member on the shank extendingaeross said slots.

Fl. friction device for sluittles consisting'ot' a tubular post open ateach of its ends, the upper end of said post being formed with a pair ofoppositely disposed slots, and an adjustable thread engaging device insaid post which has a base circular in cross .setiion which roniormablyand t'rictionally titled in the base end of the post, and a member onsaid base of the thread engaging device which is disposed across theslots said member having an end spaced from the upper end of the post.interior which is opposite to the said end to allow the thread to bepassed'down through the slots and to engage the under side of saidmember.

4. A friction device for shuttles'consisb ing of a tubular posthaving'opposice slots name to this specification in the presence of atone end, and a. removable thread engag two subscnblng wltnesses.

in" element in said post having a. part therew I of extending aczpss'each of said slots and JGSEPH L kt/K01) adaptggd to have the threadengage under Witnesses:
